I don't know anything about DDS formats.
I have a simulator programme that uses them to render backgrounds.
They come in 6 images (6 sides of a cube).
I'd like to be able to modify these images and even create my own.
However, neither the native nor this plugin can read the files (https://drive.google.com/open?id=12cwQCYD6K-l3hBWTFNoM6NWq74yqcYE2).
Any help would be appreciated. TIA
